A potential escape spot in
any chicken
fence is where the ground meets the wire.
I like using old logs that
are way past the point of firewood. Sometimes I'll lay them on top of
the wire and other times it works out better to have the log on the
bottom depending on if there's any slope to deal with.
Old boards from the broken
down house worked as the same function, but you don't get the bugs and
worms that come along with a punky log.
